A) 1/2
B) 1/3
C) 4/9
D) 27/5
Correct Answer: D
Solution :
\[\Delta E={{E}_{2}}-{{E}_{1}}=\frac{1312}{{{1}^{2}}}-\frac{1312}{{{2}^{2}}}=1312\left( \frac{3}{4} \right),\] \[{{E}_{3}}-{{E}_{2}}=\frac{1312}{{{2}^{2}}}-\frac{1312}{{{3}^{2}}}\] \[=1312\left( \frac{5}{36} \right)\] \[\therefore \] \[{{E}_{2}}-{{E}_{1}}:{{E}_{3}}-{{E}_{2}}=\frac{3}{4}:\frac{5}{36}=27:5\]You need to login to perform this action.
